He also cared for the things of God at the age of twelve (Luke 2:42, 46-47, 49). The age of twelve is the age of a boy's full growth. The boy Jesus was caring for the interest of God when He was twelve years old.
In His maturity as a man at the age of thirty, He began His ministry for God (Luke 3:23). Thirty years of age is the full age for God's service (Num. 4:3, 35, 39-40, 43-44, 47-48). In the Old Testament a man entered into an apprenticeship for the priesthood at the age of twenty-five. He learned for five years and became mature at the age of thirty. The Lord Jesus became mature at the age of thirty to carry out His earthly ministry.
From the time that He became a minister of God, He also became a man of sorrows, suffering the despising, rejection, and persecution of man (Isa. 53:3; Matt. 13:55-57; Luke 4:28-30; Matt. 26:4, 16). Throughout His whole life, He was suffering, but especially in the last three and a half years.
After He became thirty years old, He was tempted by the devil, and this temptation was under the leading of the Spirit of God (Matt. 4:1).
In that temptation He defeated the devil, and after that temptation He was ministered to by the angels (Matt. 4:11).
We can see the move of God in man as He passed through human living in the stages of human life. He was a real man in babyhood, in boyhood, and in His maturity as He ministered for God. His human living was a very particular living. It was the living of God in His move within man and through man. His living was God's living in a man, which should be our living today. The Christian living should be a living in which God lives a human life in His children.
